testo 445 - Service instrument for air conditioning / ventilation systems

Code: testo 445 0560 4450


 
Datasheet PDF, 0.92 Mb

Description

The testo 445 VAC instrument measures temperature, relative humidity, dew point, absolute humidity, degree of humidity, enthalpy, all types of air velocity (in ducts, duct openings, or extractors), volume flow, pressure, and indoor air quality.

 

Features:

  • Multi-function climate measuring instrument: measure up to 6 measurement parameters at the same time
  • Internal reading memory for up to 3,000 readings
  • Automatic allocation of the duct cross-section to the measuring location (max. 99 measuring locations)
  • Automatic mean value calculation and determination of the volume flow
